Britain is so saturated with coffee shops that the American food and drinks chain Dunkin’ Donuts has decided to skip the country altogether as it steps up its global expansion plans and concentrates, instead, on Russia and Asia.

Although Dunkin’ Donuts pulled out of Russia in the 1990s, it has returned with big plans to open more stores in a country where buying a doughnut and a coffee is becoming an increasingly popular social activity, according to Nigel Travis, the chief executive of Dunkin’ Brands, the owner Dunkin’ Donuts.
